CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 267,908, dated November21, 1882. Application filed October 12, 1882. (No model.)

To all whom it may concern:

Be it known that I, FRANK O. LYNN, of Norristown, in the county ofMontgomery and State of Pennsylvania, have invented a new and Improved(Jar-Coupling, of which the following is a full, clear, and exactdescription.

The inventionconsists in the combination, with a draw-head having a hookformed at its end, of a spring which presses the draw-head in thedirection toward the open side of the hook, and of loop-frames formed onthe top. and bottom of the draw-head, whereby two such draw-heads cancatch on each other or on the loop-frames, accordingly as the draw-headsare at the same .or different elevations above tLe track.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a perspective-view of myim proved car-couplin g, showing itattached to a car. Fig.

2 is a plan view of the under side of the same,

showing two, draw-heads coupled.

The draw-head A, which is pivoted to the under side of the car-bottom toswing on the horizontal plane, isprovided at its free end with a hook,B. The outer end of the drawhead is beveled or rounded ofi toward theshort prong of the hook, andis provided with a horizontal recess, 0,adapted to receive a couplinglink, and with pin-apertures D. Bows orloopt'rames E project from the'top and bottom of the draw-head, near theend, the outer side or shanks of the said frames being vertical. Aspring, K, secured to the car-body rests against the side of thedraw-head and presses the same catch and engage with each other.

in the direction toward the open side of the draw-head hook. A rod, H,is attached to the draw-head and to the lower end of a lever, J, 0pivoted on the end of the car, by means of which lever J and rod H thedraw-head can be drawn or moved in the inverse direction of that inwhich it is pressed by the spring K.

The operation is as follows: When the drawheads come together thebeveled ends strike againsteach other and are moved laterally from eachother. When the endsof the short prongs of the hooks have passed eachother the drawheads snap toward each other, and the books 0 As shown inFig. 2, when the draw-heads are at difi'erent elevations above thetracks the hooks catch on the frames projecting from the topsand bottomsof the draw-heads.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with the draw-head A, provided with a hookhead, B,of the spring K and the loop-framesE on the top and bottom of thedraw-head, substantially as herein shown and described, and for thepurpose set forth.

2. The combination, with the draw-head A, provided with a hook-head,B,of the spring K, the loop-frames E in the top and bottom of thedraw-head, the rod H, and the lever J, substantially as herein shown anddescribed, and for the purpose set forth.
